Sudoku Random Generator
C++, problems using return?
int main()
{
int Array[3][3][3][3]={0}; // Array is created and all elements are set to 0
int RemoveCells=0;
srand((unsigned)time(NULL)); // Resets the number used in the random number generator to give a new random number each time
SetScreen(); // Sets the Sudoku grid
ArrayAssign(Array); // Assigns Array’s elements a value
ArrayPlacer(Array); // Places the contents of Array into the Sudoku grid
Difficulty(RemoveCells);
SetPuzzleScreen(); // Sets the Sudoku puzzle grid
Hider(Array, RemoveCells); // Randomly hides around 50 cells in the Sudoku puzzle grid
gotoxy(28,48); //This is to move “Press any key to continue” below the Sudoku puzzle grid
return 0;
}
…….
My Difficulty function has RemoveCells passed in, depending on user input RemoveCells becomes 40, 50 or 60. But when I put
return RemoveCells;
at the the end, it doesnt return them, what am I doing wrong? :S
Thank you so much! That was the EXACT problem!!! 
i don’t know, because you didn’t post the code of Difficulty().
my guess is that it returns the value, but it’s not assigned in your main function. Change the code to this:
RemoveCells=Difficulty(RemoveCells);
then it should work.
